BUMrINe-ros'r.

Tea whom it may concern:

' Be it known that I, Lnwis M, LAWRENCE, a citizen of the United $tates; residing at Birmingham, in the county 10f Jefferson,

useful Improvement in Bumping-Posts, of which the following is a specification.

My invention is a buffer or bumping post arranged at the end of'jailway spur tracks tb arrest a train or carsrunning thereon, the .principal feature of which iscross anchor beams, and two pair of longitudinal beams inclined downward from the rear to the front, and top cross beams, and uprights set deep in the earth for additional anchorage. The upright in the center is the bumper proper. J N

In the accompanying drawing Figure l is a perspective view. of the structure with the front to the left. Fig. 2 is a sectional view looking fronrthe' middle to the left side. Fig. 3 is the center one of the 'uprights Which conu'irise the bumper proper.

The numerals refer to the various parts in the different views.

The rail road rails l1. l designates the railroad rails, 2 the common crossties; and 3. 4 and 5 the cross under the rails' and-spikcd to them in the; ordinary way.

Two pair of longitudinal beams 6i'6 and 77 rest on the ends of the anchor beams. Beams (1 lap over beams 7 in part. A shoulder is cut in the under edge of the front end of beam 7 and the top edge is beveled. This shoulder rests onand abuts anchor beam 4 which gives beams 6 and 7 an incline from the rear to the front.

Two top cross beams 8 and 9 placed some seven inches to the rear of anchor beam 4 and blocks 1010'betwecn the two beams. Anchor beam 4 and the rear top cross beam 9 are encircled by metal links 11 11 best seen in Fig. 2. All the joints are tied by metal links 12 -12 and lt3l3 and 1444.

In this seven inch space I set uprights 15- 15 digging deep in tlie'earth for additional anchorage. The uprights rest against the reel of anchor 4 and the front of -the top cross beam 8. The upright in the Patented Mar. 2a, iota.

center serves the douhlepurpose of bumper l6 proper and additional anchorage. It is molded with a hole ii'r the upper end of it,

see Fig. 3 This hole is-largerat the front than at theqrear and is to be fitted with a block of wood grainwise for the dra v head of the car to play out I From the foregoingit is seen that here is a tie or lock or'anchor on the earth, the

structure of which will admit of any conceiva'ble strength, can be built to any wants, stand if you want it to stand or give yet not break, plows the earth much as a snow plow plows a bank of snow.

Vhat I claim is- 1.. In- -a bumping post the combination 'with av pair of longitudinal side frames, in-

clmcdffrom the rear to the front, of trans verse members mounted thereon and spaced apart by blocks, and vertical posts having then-upper ends supported by said transverso members, a. transverse member 4 mounted beneath the said'longitudinal mem bers and lying against the front of the vertical posts,and means to tiethe transverse members together and to tie all said elements tothe side frames as described.

In a bumping post the c'ombmation with side frames mounted on transverse anchor' beams and secured thereto, of a plurality of transverse timbersmounted upon the side frames, and a vertically disposed post extending'above and below the planeof said side frames the lower end of said post being adapted to secure said bumping post against displacement substantially as described.

3. In a bumping post the combination or vertical memberscxtending below and above the plane of side members and supported at the top and rear by top cross members, and below the side members and at the front by a cross anchor member and with the means of tying'all of the elements together as described.
